' TRIO COMPANY, A CORPORATION 01?. NEW -YORK LIGHT rnoanoroa Application filed. March 133931; gseria l ito. "522,375;

The present invention relates to light projectors and especially to light projectors of considerable siz'e, for example, of'the size for 1000 or 1500 watt lamps or larger, although 51it is to be understood that the invention is not limited thereto. 7 V

The object of my invention is to provide an improved construction of casing and reflector arrangement for a projector which possesses advantages from a manufacturing standpoint and in appearance, and for a con sideration of what Ibelieve to be novel and my invention, attention is directed to the following specification and to the claims appended thereto. i

In the drawings, Fig. 1 isa vertical sectional View of a light projector embodying my invention, and F ig; 2 is a face view thereof, a part of the cover being broken away to illustrate parts to the rear ofthe cover Referring to the drawings, 1 indicates the casing or housing of the projector; 2 indicates the cover comprising the ring 3 and the lens 4; 5 indicates the reflector, and 6 indicates the recess for housing the lamp socket 7 into which the lamp 8 is screwed. The cover 2-is hinged to' the casing as-is indicated at 9 and is adapted to be fastened in position over the casing by means of suitable screw cated at 10. The lens 4 is held ring 3 by means of suitable cleats 11 fastened by screws 12. The reflector is fastened in the casing by means of cleats 13 fastened by.

screws 14 to spaced projections 15 formed at the inner edge of the casing 1. socket is mounted on a bracket 16 carried on a hinge 17 on which it may be adjusted by means of a. threaded rod 18, the threaded rod serving also to hold the bracket inadjusted position.

In connection with the construction of light projectors of the type illustrated it has heretofore been thepractice to form the recess 6 for housing the lamp socket as a projection on the top of the casing, the projec tion having an integral front wall and showing from the front of the casing. This constructionhas the disadvantage from a manufacturing standpoint that when the casing is cast the forming of the recess requires the the casing,when viewed" from the front, de-f clamps indiinthe cover.

The lamp "tighter fitting cover ich adds to the tracts fromthe appearance of the projector. According to my invention, I construct the front of the casing 1 ofa diameter such that it encloses or includes entirely the front ofthe projection 6, and'I then mount the reflector eccentrically-in the casing and correspon dingly mount the lens 4 .ec'centrically in; the f door; With this arrangement the projector,

the casing when cast can be removed directly from the mold. This decreases materially-the cost of the moldingoperation. The reflector 5 is mounted eccentrically in the casing to an j v when viewed from (the front, is round in con- 7 extent suflicient to provide room for thelamp socket, the reflector 5 having an opening 20 through which the neck of the lamp 8 e'x tends, and the lens 4 is mounted eccentrically inthe, cover so as to be concentric with the reflector.

provided with a beveled surface21' against which a beveled surfaceon the coverQfits;

This arrangement has the advantage that The casing is-round'atithe front and is I the beveled surface may be machined around I the periphery of thefc asing, and a similar surface may be machined on the door, which out detracting fromlthe iserviceability of the r 7 means that the door can be readily fitted, and Y construction, and at. the same timeprovide a more whole for the casing, ,and a; pleasing appearance for the unitas I What I claim as newand desire to secure 1 by Letters Patent of :the United States, is v c 1-. In a projector, ataperedcasing'which 1 terminates 'atitsforward end in a circular I '1 a: mounted 'e'ooen'trieally in the cover con centric with sand reflector, said cove! closing the open side of the casing and thegrecess,

In aprojector, a tapered casing which terminates at its forward. end ins, circular open 'side, a projection formed integral with the casing toprovide' arecess for thereceptioneof .3;.1z1mp support, said projection at its forward end being located within the contour ofthe c1 enlaropen-side oithe casing wherebyi said 'reeess at its forw'ard'end opens into said circular open sideQahd-said easing v having a beveled surfaoesurroundingthe open side, a circular cover for the oasingfhaving abeveledsurfaoe which engage the beveled surface oithe'ca-sing, a refleotor mounted eooentri cally said casing, andw lens for the reflector mountedecoentrica'lly said cover concentric with said reflector, i'saidoover olosding theopen sldfi of the casing and the recess.
